Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spanish onion
- Forms the edible shell that holds the filling and softens as it cooks.
- Force-meat
- Provides the savory filling that cooks through inside the onion.
- Sweet, fat pork
- Bastes the filling with its fat as it cooks, adding richness and moisture.
- Stock
- Creates the gravy and keeps the onion moist during covered cooking.
- Sugar
- Adds sweetness and promotes gentle browning in the onion and gravy.
The step that matters
Cover closely and cook over medium heat. Gentle, covered cooking traps steam so the onion softens evenly and the filling cooks through without drying or scorching. Too much heat can burn the sugar and dry the stock before the onion is tender.
